ED\ VIN T. COPELAND, OF BROOKLYN, NEW YORK:

AUTOMATIC SPRINKLER VALVE.

SPECIFICATION forming part of Letters Patent No. 369,80, dated September13, 1887.

Application filed February 5, 1887. Serial No. 226,647. (No modol.)'

To all whom, it may concern:

Be it known that I, EDWIN T. COPELAND, a citizen of the United States,residing in the city of Brooklyn, county of Kings, and State of NewYork, have invented certain new and useful Improvements in AutomaticSprinkler-Valves for Fire-Extinguishing Purposes, of which the followingis a specification, reference being had to the accompanying drawings.

My improvements relate specially to. the construction of automaticsprinkler-valves in which pressure is relied upon to keep the valveclosed or seated, such pressure being hastily released by heat orexplosion through the weakening or destruction of the supportingelements.

The object of my improvements is to provide surety of action as well ascertainty of operation through reliance upon a variety of means orchances; also to attain simplicity and cheapness of construction as wellas case of access and application.

My improvements consist in the construction of a yoke and acartridgeinclosing support for holding the valve in place in such mannerthat a charge or cartridge of burning or explosive material may beinserted without disturbing the valve or its support.

Other improvements consist in the combination of the several portionscollectively or with each other, as may hereinafter be shown anddescribed.

In the drawings, Figures 1 and 2 represent sprinkler-valves embodying myimprovements.

Similar letters of reference designate like parts in both the figures.

Fig. 1- represents a sprinkler valve in which the bottom or end ofpipe-nozzle B is kept flat and a flat valve, b, is held to its seat bythe cartridge-inclosing support A. Fig. 2 represents a sprinkler-valvein which the bottom or end of pipe-nozzle B is made concave and thevalve 12 so shaped or made of such material as to freely conform to suchconcavity. In either figure the bottom or outer portion of the yoke G atac and the neck of the cartridge-inclosing support A at e are made opento permit of the easy insertion of a charge or cartridgeof burning orexplosive port A, is already shown in my application Serial No. 205,532.

Any method of holding the valve and cartridgeinclosing support may beused, the special feature of these improvements being the means providedfor inserting an explosive charge or cartridge without disturbing thesprinkler-valve b 011 its seat.

The cartridge or charge may be inserted and the neck closed, as shown atc, Fig. 1; or the opening or neck may be closed by the cartridge itself,as shown in Fig. 2. In any case the wires (1 d are inserted to provideelectric incandescence and the burning or explosion of the containedcartridge.

0 c are cushions for taking the thrust upon the chamber A to spread itabout when such chamber is constructed of brittle material.

WVhat I claim as new, and desire to secure by Letters Patent, is

1. In an automatic sprinkler-valve, a yoke and a cartridge-inclosingsupport for the valve upon its seat, each having an opening or hole atthe outer or bottom end, through which a cartridge may be inserted orwithdrawn without disturbing the seating of the valve.

2. In an automatic sprinkler-valve, the combination of a nozzle-closingvalve, 2), a yoke having an opening at the outer or bottom end, and acartridgeinclosing support having an outer or bottom opening, throughwhich holes an explosive or cartridge may be inserted or withdrawnwithout disturbing the closing of the valve, substantially as set forth.

3. In an automatic sprinklervalve, the combination, with a pipe branchor connection, B, of valve 1), a cartridge-inclosing sup- I port, and asupporting-yoke, 0, each having at bottom or outer end, cushions c,cartridge an opening through which an explosive or E, and electric wiresd d, substantially as and cartridge may be inserted, and electric wiresfor purposes specified.
